Question

Medications that reduce stomach acid may impair the absorption of _____.​

Quizplus · Accepted Answer

Medications that reduce stomach acid, such as proton pump inhibitors (PPIs) and H2 blockers, can impair the absorption of vitamin B12. This is because stomach acid is necessary for the activation of intrinsic factor, a protein produced in the stomach that helps the body to absorb vitamin B12 in the small intestine. Without adequate stomach acid, B12 absorption can be decreased leading to deficiency. The other nutrients listed (A, C, D, and E) are not as dependent on stomach acid for absorption, and their absorption is not typically affected by acid-reducing medications.
